In general, it is not recommended to fit casing over molding. The reason for this is that casing is meant to sit flush against the wall surface, while molding is typically thicker and protrudes from the wall. When attempting to fit casing over molding, it can create an uneven and unpolished look, as the casing won’t lie flat against the wall.
Moreover, adding casing on top of molding can make the overall trim look bulky and detract from the intended appearance of both the casing and the molding. It is preferable to choose one element over the other, depending on the desired look or the specific architectural feature in question.
Alternatives to Fitting Casing Over Molding
If you want to add additional trim around a door or window that already has molding, there are a few alternatives you can consider:
Removing the molding: One option is to remove the existing molding and replace it with casing. This approach ensures that the casing sits flush against the wall, providing a clean and uniform look.
Modifying the casing: Another option is to modify the casing itself. You can shave or trim the backside of the casing to fit around the existing molding. However, this method requires precision and may not be suitable for all cases, as excessive modification can compromise the structural integrity of the casing.
Selecting complementary designs: If you wish to keep both the casing and the molding, it is crucial to select complementary designs that work well together. Ensure that the sizes, shapes, and styles of the two elements coordinate and create a harmonious look.
While casing and molding are both essential elements in home design, it is generally not advisable to fit casing over molding. These two decorative trims have distinct purposes, sizes, and shapes, which can lead to an unappealing result when combined. When choosing between casing and molding, it is best to consider the specific application, desired look, and overall aesthetic of the space.
